- The initialVersions property and its handling are removed because they are unused internally. (7.0.0) — [release notes](https://github.com/changesets/changesets/releases/tag/%40changesets/types%407.0.0)
- Supported Node versions are now ^22.11 || ^24 || >=26. (7.0.0) — [release notes](https://github.com/changesets/changesets/releases/tag/%40changesets/types%407.0.0)

### New APIs and options

- Package and Packages are now exported from @changesets/types for use instead of the types from @manypkg/get-packages. (7.0.0) — [release notes](https://github.com/changesets/changesets/releases/tag/%40changesets/types%407.0.0)

### Tooling

- Versioned prerelease changesets are stored in .changeset/pre/ instead of accumulating in the root and tracking IDs in pre.json; existing pre.json auto-migrates on the next changeset version run or changeset status call.
